perFrameMetrics
Optionally choose one or more per frame metric reports to generate along with your output. You can use these metrics to analyze your video output according to one or more commonly used image quality metrics. You can specify per frame metrics for output groups or for individual outputs. When you do, MediaConvert writes a CSV (Comma-Separated Values) file to your S3 output destination, named after the output name and metric type. For example: videofile_PSNR.csv Jobs that generate per frame metrics will take longer to complete, depending on the resolution and complexity of your output. For example, some 4K jobs might take up to twice as long to complete. Note that when analyzing the video quality of your output, or when comparing the video quality of multiple different outputs, we generally also recommend a detailed visual review in a controlled environment. You can choose from the following per frame metrics: * PSNR: Peak Signal-to-Noise Ratio * SSIM: Structural Similarity Index Measure * MS_SSIM: Multi-Scale Similarity Index Measure * PSNR_HVS: Peak Signal-to-Noise Ratio, Human Visual System * VMAF: Video Multi-Method Assessment Fusion * QVBR: Quality-Defined Variable Bitrate. This option is only available when your output uses the QVBR rate control mode.
